Locking system and method for electronic device

Abstract

A locking system includes a radio frequency identification (RFID) tag encoded with a first code, an antenna, an RFID reader, a storage unit storing a second code, and a microprocessor. The RFID reader receives a radio-frequency signal emitted from the RFID tag via the antenna. The radio-frequency signal includes identification of the first code. The microprocessor compares the first code and the second code, and locks an electronic device when the first code does not match the second code.

1 . A locking system comprising:
 a radio frequency identification (RFID) tag encoded with a first code;   an antenna;   an RFID reader receiving a radio-frequency signal emitting from the RFID tag via the antenna, wherein the radio-frequency signal comprises information of the first code;   a storage unit to store a second code; and   a microprocessor to compare the first code and the second code, and controls an electronic device according to a comparing result between the first and second codes.   
     
     
         2 . The locking system of  claim 1 , wherein the antenna, the RFID reader, the microprocessor, and the storage unit are mounted in the electronic device. 
     
     
         3 . The locking system of  claim 1 , wherein the RFID reader, the microprocessor, and the storage unit are connected to a power supply unit. 
     
     
         4 . The locking system of  claim 1 , wherein on the condition that the first code matches the second code, the microprocessor activates the electronic device. 
     
     
         5 . Te locking system of  claim 4 , wherein that the first code matches the second code means that the first code is the same as the second code. 
     
     
         6 . The locking system of  claim 1 , wherein on the condition that the first code does not match the second code, the microprocessor deactivates the electronic device. 
     
     
         7 . The locking system of  claim 6 , wherein that the first code does not match the second code means that the first code is different from the second code. 
     
     
         8 . A locking method comprising:
 an antenna scanning a radio frequency identification (RFID) tag encoded with a first code;   a RFID reader receiving a radio-frequency signal emitted from the RFID tag via the antenna, wherein the radio-frequency signal comprises identification of the first code;   transmitting the radio-frequency signal to a microprocessor;   reading a second code by the microprocessor;   comparing the first code and the second code by the microprocessor; and   controlling an electronic device according to a comparing result between the first and second codes.   
     
     
         9 . The locking method of  claim 8 , wherein controlling the electronic device comprises:
 on the condition that the first code matches the second code, the microprocessor activates the electronic device.   
     
     
         10 . The locking method of  claim 8 , wherein controlling the electronic device comprises:
 on the condition that the first code does not match the second code, the microprocessor deactivates the electronic device.
